z/VM 5.2 is limited to 128 sessions, but as Ray alludes, you need the test 
fix for still-open APAR PK51954 (SSL server crashes when multiple 
connections are active).

z/VM 5.3 has been tested with 2000 sessions using the beta version that 
contains fixes for the follwing still-open APARs:
 PK52298 - SSL Server Connection Limit Relief 
 PK53928 - SSLADMIN Command Updates for SSL Connection Limit Relief
 PK53932 - TCP/IP Server Updates for SSL Connection Limit Relief
The 2000 sessions is not an architected limit, but just the highest number 
we've tested.  These fixes will not be back-ported to z/VM 5.2.

Anyone who is thinking about using the SSL server on z/VM should touch 
base with Support to get the fixes for these.  Folks using the SSL server 
appliance from Sine Nomine should get in touch with them for updates.
